UFO Explodes over tropical island

The Vietnamese new agency has reported that residents found shards of grey metal 1.5 meters in length shortly the Cambodian government retracted reports of a mysterious plane crash. Before anyone gets excited, this is probably some kind of secret program by the Vietnamese government rather than some alien saucer. These crash incidences have happened in America before a few decades ago and nothing came out of them.

Besides if aliens have been coming to our world from decades, perhaps centuries, why would they not make themselves known to us? They’d either be friendly or hostile and either way, they would make themselves known. If they were hostile, they’d probably come in with guns a-blazing and either destroy or enslave us. If they were friendly, they’d open up negotiations with us. Unless you believe the government has alien contacts and is not informing us, its quite unlikely that these ‘aliens’ keep visiting earth without having us notice them.
